Sponsor's own description
The ability to assess ingestion in fine detail over the time course of a liquid meal allows for comparison of early and late meal features of drinking and may help dissociate manipulations (surgical, neural, pharmacological, etc.) that affect orosensory properties from those that are modulating postoral processes in the control of intake. The aim of the study is to asses microstructural changes in liquid meal intake over 1-year in severely obese patients after Roux-en-Y gastric bypass (RYGB).
